Reducing strain in heterogeneous quantum devices using atomic layer deposition
Oscar W. Kennedy, James O'Sullivan, Christoph W. Zollitsch +3
We investigated the use of dielectric layers produced by atomic layer deposition (ALD) as an approach to strain mitigation in composite silicon/superconductor devices operating at…
Spin coherence of near-surface ionised Te donors in silicon
Mantas Šimėnas, James O'Sullivan, Oscar W. Kennedy +8
Impurity spins in crystal matrices are promising components in quantum technologies, particularly if they can maintain their spin properties when close to surfaces and material int…
Electric-field-driven conductance switching in encapsulated graphene nanogaps
E. Pyurbeeva, J. L. Swett, Q. Ye +2
Feedback-controlled electric breakdown of graphene in air or vacuum is a well-established way of fabricating tunnel junctions, nanogaps, and quantum dots. We show that the method i…
Random-access quantum memory using chirped pulse phase encoding
James O'Sullivan, Oscar W. Kennedy, Kamanasish Debnath +9
As in conventional computing, key attributes of quantum memories are high storage density and, crucially, random access, or the ability to read from or write to an arbitrarily chos…
